WEATHER-STRIP.

SPECIFICATION forming part of Letters Patent No. 248,832, dated October 25, 1881.

Application filed May Q4, 1881.

To all wiz-0m t may concern:

Be it known that I, MoR'rIMER S. HARSHA, of Chicago, Illinois, have invented certain new and useful Improvements inVeather-Strips for Door-Bottoms; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to weather-strips intended for the bottoms of doors; and it has for its object to provide a construction at once durable, reliable,and convenientof application to right or left hand doors, as maybe required.

To this end itconsistsin the combination and arrangement ofparts hereinafter described, and

pointed out in the appended claim.

In the drawings, Figure 1 is a fragmentary rear view of my improved strip detached. Fig.

2 is a transverse Vertical section thereof applied to the door. Fig. 3 is a horizontal section of a door-frame and a door having my improved strip appliedlthereto. Fig. 4 is a rcar elevation of the detached strip, showing' the relativc positions of the parts when the door is open.

A represents a door, hinged to the frame B, having the usual stop or head, O. B' is the threshold.

D is a molding, having a broad rabbet, d, cut in its lower rear face, and having, preferably, the external sectional contour shown in Fig. 2.

E is a bar of equal length with the molding, fitted to move freely in the rabbet d, and bearing on its lower edge the closing-strip F, of rubber orother suitable material. The bar E is joined with the molding D by the flat connect- 40 ing-linl-:s G G, set in the notches n n, so as to clear the door when the strip is in place, and screwed to the several parts loosely, so as to permit the bar E to move freely. The links G are so applied, as shown, that where their pivotal points (or the screws 8 8) are sqnarely opposite each other there will be a considerable space between the edge of the bar E and the top of the rabbet, and the ends of the molding and bar will be flush, all as shown in Fig. 1. Being thus connected, a nearly horizontal ex- (No model.)

panding-spring, H, inserted in the opposite notches (t c of the several parts, so as to bear atonc end against the molding and at the other against the bar, as also shown in Fig. 1, operatcs to slide the barE longitndinally in the rabbet and to throw one end thereof beyond the end of the molding D. The parts D and E, connected and Operating as described, are cut of length to freely enter between the opposite beads C of the door-frame, and the molding D is screwed to the outer face of the door,

at its lower edge, in proper position for this pnrpose. The spring H is applied to the parts D and E, so as to throw out the bar E at the hinged side of the door, whereby, when the door is being closed, the protrudin g end of said bar will strike the bead O, and will be forced inward anddownward to close the space or passage beneath the door.

The weather-strip is adapted to be readily applied to either a right or a left hand door by providing two oppositely-directed sets of notches, a c, as shown in Fig. 1, and also providing a movable eXpanding-spring, H, which may be inserted in either set ofnotohes or shifted at pleasnre from one to the other. Strips of suitable length for all ordinary doors thus constructed may be conveniently fitted and applied to the door by the purchaser without the aid of a skilled oarpenter.

I am aware that a similar weather-strip has been made, having` the relatively moving parts joined by fiat rubber strips set in the Vertical inner faces ot' the parts and tacked at their ends thereto under tension, so as to draw them together. Such Springs not only soon lose their eficiency, but they require additional parts as fastenings, and are liable to become detached and useless. -By means of an expanding-spring on the other hand, and by arranggo ing the same between opposingshoulders made by notching` the opposite horizontal meeting faoes of the relatively moving parts, as described, so as 'to push instead ot' to pull, all

special fastenings are dispensed with. Moreover, being held in place by its own expansive force alone, when thus applied, the' spring is readily removablc, and by providing two sets of oppositelydirected shoulders or notches said spring may be convenientlyapplied to give roo' the proper throw to the bar E to suit the door applcahle to either a right or left hand door, :o

'to which it is to be attached. as set forth.

I claim as my invention- In testiinony that I olaim the foregoing' as Theweather-strip described,consistingof the my invention I affix my signature in presence 5 parts D and E F, connected by links G, and of two witnesses.

provided with two sets of opposite notches, MORTIMER S. HARSHA.
